I have used most of them myself. Some more than others, but i still fall back to the Gb2. I have just had such great luck with it. I also run a GP extreme for my PI detector. I really do love both of them. The extreme isnt quite up to par with the new PI's, BUT with todays coil technologies, it is great. The Gb2 is my personal favorite though. Good luck on your search.

Since my last post in April on this subject, I have actually used and love the Gold Hog mat. It has raised my recovery of fine gold and bigger gold by huge numbers. BUT.....i have yet to get rid of the miners moss. Maybe just stuck on the moss i guess. I run 3 pieces(18") of mat in the top half of my keene highbanker and the rest moss and either riffles or expanded metal, depending on where i am working. But as for the mat, i am now a believer.

Sure, it is casluicebox.com. Haha i have no affiliation with them. I agree with one of the comments up above about not having enough time in the drum to wash. That is one thing i might have a problem with if i buy this drum. BUT they will build anything you want if you ask them. The prices are awesome for they are offering. I will try them out and if i have to i will modify it for what i want. I am going with their 10" x 36" drum. $150 bucks is a good price for the materials they use.
